Surplus plutonium for power reactor fuel: What’s on offer
The Department of Energy has a plan for private companies to “dispose of surplus plutonium”—about 19.7 metric tons in both oxide and metal forms—by “making the materials available for advanced nuclear technologies.” A Surplus Plutonium Utilization Program request for applications (RFA) issued October 21 describes the plutonium on offer, and the “thresholds” prospective applicants must meet.

The reactor attributes of the compact, high beta RFP are as needed today as when the RFP was conceived. Confinement is a dominant scientific issue at present, In the past several years magnetic fluctuations have been shown experimentally to drive anomalous transport. From an understanding of the cause of transport, it is expected that flattening of the current density profile should suppress fluctuations and transport. Inductive current profile control has succeeded in reducing fluctuations, and doubling the energy and particle confinement times. For steady state current profile control, electrostatic current injection (dc helicity injection) is under preparation and rf current drive (fast wave and lower hybrid) has been shown to be feasible.
